Abstract
Cotton Leaf Curl Virus (CLCuV) is serious danger in excellent cotton cultivation in Pakistan. Due to the lack of CLCuV tolerance in upland cotton, the most economical and lasting approach to grab this serious matter is to introgress resistance in upland cotton from wild species. Desi Cotton (Gossypium arboreum L.) has resistance against CLCuV. An upland cotton cultivar MNH-1050 (Bt.) has been evolved by interspecific hybridization for CLCuV tolerance at Cotton Research Institute (CRI), Multan, Pakistan. It was developed through introgression [BC5F6 (Gossypium hirsutum L. × Gossypium arboreum L.) × MNH-886] × MNH-988 during 2008-2009 at CRI Multan. To manage boll shedding, a combination of gibberellic acid (50 mg/l) and naphthalene acetic (100 mg/l) acid was applied. The variety consistently outperformed than the standard varieties in National Coordinated Varietal Trial (NCVT) Punjab during two consecutive years 2020 and 2021. It produced 8.85 % and 29.7 % higher yield than standard varieties CIM-602 and CYTO-124 respectively in NCVT during 2019-2020. It proved as the more tolerant strain against CLCuV, with 62% and 65% lesser CLCuV incidence than that of standard variety IUB-13 in Preliminary Yield Trial (PYT) and Advance Yield Trial (AYT) during 2018-2019 at CRI Multan. It had relatively lesser attack of Jassid, pink boll worm and complete resistance against other boll worms i.e., army worm, spotted boll worm, american boll worm. MNH-1050 was approved as single gene Bt. cotton variety with CLCuV tolerance, heat tolerant, early maturity, low input efficient, specific pest resistance, high yield potential and most adapted for wheat-cotton cropping rotation. It has fluffy opening with ease in picking, high Ginning Out Turn GOT% (40.5%) with refine fiber characters i.e., staple length (28.35 mm), good fiber fineness (4.58 µg/inch) and fiber strength (29.11 g/tex). It fulfills various purposes of industry. It is most suitable for cultivation on marginal land and water deficient areas.
